This is a pretty easy fix... basically what is happening is your swash plate is not leveled. Dont worry, it's simple enough to fix.... here's how....

place your cx2 with the tail end facing you... looking under the bottom blades, attached to the swashplate is a left and right push rod that is attached to the servos inside the copter...

The pushrod on the left (remember looking from the back side) controls the forward/reverse. the pushrod on the right side controls the pitch right or left.....

To correct your forward motion, you will need to pop off from the swashplate ball joint the left (forward/reverse) push rod....
Turning the head of the pushrod in a closkwise direction to increase reverse (to level it out) you will want to make about two full turns on that pushrod.

Stop, reconnect everything and see how she hovers..... Be sure to set your trims on the transmitter remote control to center positions...

continue to turn the rods as necessary until you can give her gas and she hovers perfectly.....

Also make sure your flybar (the top little metal bar) is freely tilting back and fourth, otherwise you will get whats called TBE and it can make mechanically tuning (which is what you will be doing by turning the push rods) impossible.

Good luck, and just holler if you have further questions....

Have Fun!
